概述 >

Description:

Anti-TagFP, AlpSdAbs® VHH(Biotin) is designed for detecting TagFP fusion proteins. Anti-TagFP, AlpSdAbs® VHH(Biotin) is based on monoclonal, recombinant, single domain antibody to TagFP coupled to Biotin, and Anti-TagFP, AlpSdAbs® VHH(Biotin) detects the TagFP selectively, no reactivity with other proteins.

Immunogen: TagFP

Conjugate: Biotin
Specificity: TagFP(TagRFP/TagBFP)
Cross-Reactivity: Highly selective for TagRFP/TagBFP. Does not cross-react with common GFP or dsRed derivatives.
Purity: Recombinant Expression and Affinity purified
Concentration: 1mg/ml
Buffer: 10mM PBS (pH 7.5), 0.05% sucrose, 0.1% trehalose, 0.01% proclin300

Background:

TagRFP is derived from the Entacmaea quadricolor fluorescent protein TurboRFP (a random mutant of eqFP578), with mutations of R162E, Q166D, S180N, F198V, F200Y at the hydrophilic interface. TagBFP was derived from TagRFP with the some mutations. TagRFP/TagBFP has a high fluorescent quantum yield (Φfluo 0.48) and is widely used for fluorescent imaging. For biochemical analysis including mass spectrometry and enzymeactivity measurements.

Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.
